Digital Audio Extender

The MuxLab Digital Audio Extender Kit (500086) is a versatile digital audio standards extender and converter*.

The product allows one (1) Digital Coax (S/PDIF),
or Digital Optical (TOSLINK) source to be connected to a Digital Audio Receiver supporting either Digital Coax (S/PDIF),
or Digital Optical (TOSLINK) inputs.
Outputs on the 500086 receiver unit are simultaneous.

The audio transmission signal can be distributed to up to a distance of 500 ft / 150m in a point-to-point configuration over single Cat5e/6.

The extender supports most standards to transmit two channels of uncompressed lossless PCM audio or compressed 5.1/7.1 surround sound,
such as Dolby® Digital Plus or DTS-HD High Resolution Audio (multichannel digital audio Dolby Digital® 5.1, DTS, and Dolby® True HD).

* For a Digital Audio Standards Converter without extension over Cat5e/6, please see part number: 500087.
